About CGD

What is the Citrus Genome Database?

The Citrus Genome Database, known as CGD, is a USDA and NSF funded resource to enable basic, translational and applied research in citrus. It houses genomics, genetics and breeding data for citrus species and organisms associated with HLB.   It is built by the  Mainlab at Washingotn State University using the open-source, generic database platform Tripal

Why do we need a Citrus Genome Database?

Although there is wealth of citrus genetic research information, there is still a need for a system that can organize, filter and provide analysis on the available research to be directly applied in breeding programs. The idea of creating this database emerged from several group discussions, in which scientists, breeders, data curators, university professors and bioinformaticians started working on the publicly available genetic and genomic information to make it available for practical use in breeding programs.
